2. Discussion of the Related Art

An ornamented button such as cuff buttons should be designed to havemany different kinds of ornaments able to be selected according to tasteof user, so that the manufacturing cost becomes relatively high.

Therefore, many methods of making many different kinds of ornamentedbuttons are proposed in a manner to combine one selected from many topornamented parts with a regular base body in order to make many kinds ofornamented button at a low cost and with ease.

For example, one of proposed ornamented buttons comprises a top part, abase part and a ring for strings wherein the ring for strings isinserted into the base part and fixed on the top part at the backsidethereof (Japanese Tokkaihei 11-225807 and 11-235207).

In an another case, a ring for strings is formed on a backside of a toppart and is inserted into a base part and fixed thereto by stopper andso on (Japanese Patent No. 2724304).

In a further case, a top part is provided at a backside with a concaveand a groove at an inside thereof while a plate base part is providedwith string holes wherein just only a periphery edge of the base plateis engaged with an inside groove of the top part (Japanese Tokkaihei10-113204)

SUMMARY OF THE INVENTION

In cases of the above references 1 to 3, the ring for strings isprotruded at the backside of the base part, so that it is not easy toattach the button to the clothes in a predetermined direction.

In case of reference 4, there is no attachment problem caused by thering for strings, but engagement between the periphery edge of the baseplate and the groove of the top part is not so strong that the top partis sometimes lost accidentally.

Considering the above problems, the invention is to solve the problemsand provide a simple structure ornamented button with designchangeability according to the user taste, position and opportunity andalso uneasy detaching characteristic in spite of easy attaching.

According to a first aspect of the invention, there is provided aseparable ornamented button which comprises two parts engaged with eachother into one body, one being a top ornamented part and the other abottom part provided with string holes, wherein the top part comprisesan ornamented center portion and a periphery portion forming a receivingconcave at the backside thereof having a rocking groove or protrusion atan inside sidewall while the bottom part comprises a center flat portionprovided with string holes and a periphery ring sleeve having aprotrusion or groove at an outside sidewall, when the ornamented toppart is engaged with the bottom part, the periphery ring (short) sleevewall of the bottom part getting a tight contact to a periphery wall ofthe receiving concave and the rocking groove or protrusion of the ringsleeve of the bottom part being engaged with the correspondingprotrusion and groove of the receiving concave of the top part.

Furthermore, according to a second aspect of the invention, there isalso provided a separable ornamented button which comprises two partsengaged with each other into one body, one being an ornamented top partand the other a bottom part provided with string holes, wherein theornamented top part comprises an ornamented center portion and aperiphery ring (short) sleeve provided with a rocking protrusion orgroove at an outside sidewall while the bottom part comprises a flatcenter portion provided with string holes and a periphery cover portionhaving a receiving concave provided with a rocking groove or protrusionat an inside sidewall when the ornamented top part is engaged into thebottom part, the periphery ring sleeve wall of the top ornamented partgetting a tight contact to a periphery wall of the receiving space andthe rocking groove or protrusion of the ring sleeve of the topornamented part being engaged with the corresponding protrusion andgroove of the receiving concave of the bottom part.

According to the present invention, the top ornamented part is tightlyattached to the button body with a broader contacting area of both thesidewalls and an engaging area between the protrusion and the groove, sothat the ornamented part cannot be detached with ease even if more orless impact is applied to the top ornamented part.

Further, in a preferred embodiment of the ornamented button, the ringsleeve of the bottom part or the top part has a spread wide end providedwith sufficient end area abutting to an area of the receiving concave,so that the ornamented part cannot be unexpectedly detached or removedfrom the bottom body fixed on the clothes.

Furthermore, the bottom part with string holes can be easily sewed onthe clothes and then the top ornamented part can be engaged with thefixed bottom part, so that we can select a preferred top ornamented partfrom many and attach the selected top ornamented part according to ourtaste or our request with ease.

If we can use a regular one for the button body and select a preferredone from many top ornamented parts, we can enjoy a variety kind of thebuttons by our preferred combination of the top ornamented part and theregular body at a lower cost.

In order to prevent from loss of the top ornamented part by accident, itis preferred that the broad engaging area between the top part and thebottom is formed.

In such cases, when the two parts are engaged, the receiving concave ofthe top ornamented part engaged in the sleeve periphery of the bottombody will have a tightly engaging area. Contrary to this, in case of asleeve periphery of the top ornamented part engaged in a receivingconcave of the bottom body, they will have a tightly engaging area.

In a preferred embodiment, the top ornamented part and the bottom partcan be made of any materials such as metal, plastics, glasses andcomposite materials.
